Do not poll the asynchronous and serial interfaces on Cisco access servers. The reasons for this
recommendation include:
As remote users dial in to an access server, it is normal behavior for asynchronous and serial
interfaces to regularly go up and down.
On an average 20-minute call, one modem normally produces three alerts. At approximately 6 alerts
per hour, one modem can produce up 144 events each day. One Cisco AS5800 fitted with 1296
modems can produce up to 186,624 modem events per day.
To unmanage the asynchronous and serial interfaces for a Cisco access server, follow these steps:
From the top-level map, double click on an access server icon. The available interfaces and ports appear.
Color legend:
Green—The port is managed, and it is up.
Blue—The port is managed, but it is administratively down on the Cisco IOS.
Tan—The port is unmanaged.
Red—The port is managed, but it is in a down state.
